ACT Math Estimation Strategies Quiz

What is the main advantage of using estimation in the ACT Math section?

• It helps in eliminating unrealistic answer choices.

• It reduces the time limit for each question.

• It allows you to skip questions.

• It guarantees a correct answer.

In the example of the discounted shirt, why is the answer choice of $364 considered unrealistic?

• Because it is too low for a $55 shirt.

• Because it is a result of incorrect calculations.

• Because it is the exact price after discount.

• Because it is the original price of the shirt.

How can you improve your odds of guessing correctly after eliminating unrealistic answer choices?

• By narrowing down to fewer options.

• By guessing randomly.

• By choosing the first option.

• By skipping the question.

When approximating values in equations, what is a key strategy to use?

• Use a calculator for every step.

• Ignore the equation entirely.

• Choose numbers that are easier to work with.

• Use exact numbers only.

In the Celsius to Fahrenheit conversion example, why is it beneficial to approximate 21°C as 20°C?

• It makes the calculation more complex.

• It simplifies the calculation process.

• It provides an exact answer.

• It avoids using a calculator.

What is a useful tool for approximating geometry problems on the ACT?

How can you use your answer sheet to help with geometry problems?

• By writing down formulas.

• By using it as a makeshift ruler.

• By folding it into shapes.

• By drawing new diagrams.

What is a handy trick for dealing with angles on the ACT?

• Ignoring angle measurements.

• Drawing angles freehand.

• Using the right angle on your answer sheet.

• Using a calculator to measure angles.

What is the overall benefit of practicing estimation and approximation skills for the ACT?

• It guarantees a perfect score.

• It helps in narrowing down answer choices.

• It allows skipping difficult questions.
